This is something I haven't been able to find in the TS7250 manual.
Is there any warning of a powerfail?
I assume there's a few milliseconds between losing the external 12V supply and
the
processor stopping.
If I have a shutdown script that wants to write a very small file to Flash when
the power fails,
will it get executed?
I'm not going to use a battery and do some complicated sutff, I am just curious
if it is easy or
not.
There's one value held in memory that I would like to preserve across (planned
or otherwise)
reboots, and I don't want to write it to Flash every time it changes.
